Ivan's favorite colors are \blue{\text{blue}}blue and \green{\text{green}}green. He has \blue{\text{1 blue shirt}}1 blue shirt,

Ivan

Answer:

P(A or B) = 2/3

Step-by-step explanation:

Blue Garments = 1 blue shirt, 1 blue hat, 1 blue pair of pants

Total blue garments = 3

Green garments= 1 green shirt, 1 green hat, 1 green pair of pants

Total green garments = 3

Total no. of garments = blue garments +green garments = 6

A = event that Ivan selects a green garment

P(A) = Favourable outcomes/Total no. of outcomes

P(A) = 3/6

B = event that Ivan chooses a pair of pants

P(B) = 2/6

We need to find P(A or B) = P(A∪B)

By formula, P(A∪B) = P(A)+P(B)-P(A∩B)

P(A∩B) = Probability that a green pair of pant is chosen = 1/6

P(A∪B) = 3/6+2/6-1/6

= 4/6

=2/3

The diameter of a round skating rink is 18m. Find the circumference of the rink to the nearest meter.

Ratling [72]

As the diameter is 18, a radius is half the diamater ergo the radius is 9.

Use the circumference formula:
$2 \pi r$

So, adapted it would be:
2 * π * 9 which would be 56.7.

The circumference is 57m.

Hope this helps!
